CONTROLLING DEVICE FOR RADIATORS.

Specification of Letters Patent.

Patented Jan. 26, 1 91 To all whom it may concern Be it known that we, Fnrrz Rrrrnn VON I)()RMUS, engineer, of Marxergasse No. 1, Vienna, III, and JULIUS FLmsciIMANN, engineer, of Praterstrasse 66, Vienna, II, Austria-Hungary, have invented an Improvement in Controlling Devices for Radiators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

It is ordinary in the art of heating by steam or other fluid mediums to connect the radiator with the fluid conduit by two separate pipes or branches, in each of which is located a controlling element, whereas in the main conduit between the points at which the branch pipes oin the main another valve member is located so that by controlling the latter a flow of the heating medium through the radiator may be effected independent of the direction of the flow in the main, whereby the intensity of the radiator heating is controlled irrespectively of the direction of flow through the radiator.

According to the present invention the control in systems where the heating medium may flow in either direction through the main and the radiator is obtained by a controlling member common for both, the flow branch to the radiator and the return branch. This is rendered possible by leading the medium through the controlling member to and from the radiator. Moreover the controlling member is constructed in such form that when the connection between the main and the-radiator is interrupted through it, it will render it impossible for the heating medium to further affect the radiator so that the latter is able to quickly cool ofl.

In order to obtain the results previously pointed out the controlling member consists preferably of a cylindrical. slide valve with two completely supported chambers which are in turn provided with inlet and outlet ports, whereby this valve member is movably disposed in one or two casings which casings are connected with the flow and return flow pipes ofthe radiator. By properly moving this slide valve into the hot position one of these chambers establishes a connection between the flow pipe of the radiator and the flow branch connecting the valve casing with the main, while the other chamber connects the return b much of the radiator with the return branch from the casing to the main. On the other hand when the slide is moved into the cold position the ports of its chamber are vented to the outside, where by it is rendered impossible that, for instance, steam may leak into the radiator and produce an undesirable slow heating of the radiator.

In order to produce a flow of the heating medium through the radiator when its controlling valve has been properly opened, as mentioned above, the branches connected to the main are, at the points at which they lead into the main, provided in well known manner with nozzles, deflectors or similar means by which a suction or pressure, or also a suction and pressure is exerted upon the contents of the radiator. In order to produce a suction and a pressure and also to permit a flow of the heating medium through the radiator in either direction according to the direction in which the medium flows through the main the nozzles or deflectors are arranged so that the deflector of one branch is directed against one direction of flow and the one of the other branch directed against the other direction of flow.

Several illustrative embodiments of our invention are represented by way of example in the accompanying drawing, wherein Figure 1 is an elevation showing our improved regulator comprising branches for connection to the main heating pipe and radiator, Fig. 2 a transverse section taken mainly on the line A-A in Fig. l, but distorted in part to follow the apex of the branches 2 and 8, Fig. 3 a transverse section taken partly on the line B-B in Fig. 1, but distorted in part to follow the apex of the branches 7 and 8, Figs. 4;, 5 and (i are longitudinal sections showing the regulator in three different positions; Figs. 7 and 8 are like views showing two modified forms of regulator.

The general construction of the valve as shown in Figs. 1 to S is as follows: The pipes 2 and 3 branching from the heating pipe 1 open into the section or box -lof the valve, while pipes 7 and 8 leading to the radiator branch off from a second section or box 6 which is separated in space from the former box and rigidly connected therewith by a web 5. A tubular valve or pipe 9, closed at both ends and guided tightly in stufling boxes, passes through these two sections. This valve is internally divided into two chambers or spaces which are completely separated from one another and, in the illustrative embodiment shown in Figs. 1 to 6, are formed by a second pipe 10 arranged, for this purpose, in the tubular valve in such manner that it leaves free at each of its two ends a space having a diameter equal to that of the internal diameter of the outer pipe or valve 9 and shut off by flanges 11 from the annular chamber between the two pipes. The outer pipe or valve 9 is provided at its two ends with ports 12, 13 and 14, 15, of which the ports 12, 14 can be connected with the outer chamber 16 and the outer ports 13, 15 with the inner chamber 17,. their positions being such that the ports 12, 14 of the outer chamber 16 register, when the valve is open for heating, as F ig. 4 shows, with the ends of the branch pipes 3, 7 leading to the valve and to the radiator, respectively, while the ports 15, 13 of the inner chamber 17 register with the ends of the branch pipes 8 and 2 leading to the radiator and to the valve, respectively. Therefore, the heating medium, 6. g. steam, passing from the main pipe 1 into the branch pipe 8 can pass through the port 12 into the outer annular chamber 16 in the valve and thence through the port 14 and the pipe 7 to the radiator, whence it then flows back through the branch pipe 8 and the port 15 into the inner chamber 17 and thence through the port 13 and the branch pipe 2 into the main pipe 1, as indicated by the arrowsin Fig. 4. In order, however, more certainly to cause the steam to circu late in the radiator, we provide at the mouths of the branch pipes connected to the pipe 1 curved deflectors 18, 19, of which the one is directed opposite to the direction of flow of the steam and the other in the direction of the flow thereof, so that, on the one hand, steam is directed into the one branch, and in consequence of the flow of the steam, conducted into the radiator and, on the other hand, in consequence of the flow of steam in the main pipe, steam is sucked up out of the other branch at the other defiector, and steam is thereby caused to circulate through the radiator. By suitably shiftingthe valve axially its ports 12, 14 and 13, 15 can be closed more or less and in this manner the quantity of the steam flowing through the radiator or the intensity of the heat can be regulated. If the flow pipe to the regulator is to be closed without, how ever, connecting the radiator with the atmosphere and thereby making it cold, the

valve is shifted in the direction of the arrow out of the position shown in Fig. 4 into that shown in Fig. 5, so that the ports become covered by the packing and consequently the chambers 16, 17 are shut ,ofi' from the branch pipes and these from one another. For the purpose of making the radiator cold the valve 9 is lengthened at its free end beyond the casings 4, 6 and this extension 20 is provided with ports 21, 22 7 so placed that, when the valve is pushed into the position shown in Fig. 6, these ports are in open relation with the pipes 7, 8 of the radiator and the other ports 12, 14 and 13, 15 open into the atmosphere, so that not only the radiator is connected with the atmosphere, but the connection between it and the heating pipe 1 is quite interrupted, so that no steam can possibly flow into it.

Fig. 7 shows a valve which is not divided longitudinally, as in the hereinbetore described constructional form, but transversely by a wall or partition 23 into two adjacent chambers 16, 17, serving as ducts, of which each has a branch pipe 7, 8, respectively, to which the radiator is connected by means of flexible tubes or the like. In the position of the valve when the radiator is to be heated the steam flows out of the main pipe 1 through the branch pipe 2 and the port 12 into the chamber 16, thence through the branch 7 to the radiator, when it returns through the branch 8 into the chamber 17, and thence through the port 13 and the branch pipe 3 into the pipe 1. By shifting the valve 9 longitudinally its ports can be partially closed, or, for the purpose of shutting off the heat from the radiator, entirely closed, and, when displaced still further longitudinally, connected with the atmosphere, in which event the radiator is connected with the atmosphere by way of the two branches 7 and 8, the two chambers 16 and 17 and the ports 12, 18 which now open into the open air, While the ends of the pipes 2, 3 110 are tightly closed by the valve.

The form of regulator represented in Fig.

8 differs from that just described only in the two boxes 4, 6 of the valve shown in Fig. 7 being united to form one member, the mode 5 of operation of the regulator being exactly the same. These two forms of valveshown in Figs. 7 and 8 are particularly suitable when the radiators are at a somewhat considerable distance from the main heating 120 pipe.
